Create xml from attributes in a text file

Question

`I am doing in C#. I have certain elements and attributes. In addition to this certain attributes I need to create dynamically at run time. These attributes are kept in a text file. At run time these attributes have to be picked up and based on all these attributes xml should be generated. Currently I am getting xml as :

 <btm>
 <test testin="abc" isform="true" address="0" compressionType="9">
 <advancedSettings>
 <AdvancedSettings name=" TimeIntervalMin"/>
 <AdvancedSettings name=" GroupID"/>
 <AdvancedSettings name=" Blabla2"/>
 </advancedSettings>
 </test>
 </btm>

Ideally I want

 <btm>
 <test testin="abc" address="0" Type="9" TimeIntervalMin=""          GroupID="" Blabla2="" >
 </test>
 </btm>`

Those shown in advanaced settings are got from text file. How to do this.

My code:

 public class AdvancedSettings
 {
      [XmlAttribute]
      public string name { get; set; }
      public string value { get; set; }

 }
 [XmlRoot]
 public class btm
 {
     [XmlElement("test")]
     public List<info>information;
 }
 public class info : ISerializable
 {
    public info() { }
    [XmlAttribute]
    public string ID { get; set; }
    [XmlAttribute]
    public int Address { get; set; }
    [XmlAttribute]
    public int comType { get; set; }

    public List<AdvancedSettings> advancedSettings = new List<AdvancedSettings>();
}

This is wrong I know. BUt I dont know how to correct it.Please help.

<btm>
<test testin="abc" Address="0" compressionType="9">
<advancedSettings>
<AdvancedSettings name=" TimeIntervalMin"/>
<AdvancedSettings name=" GroupID"/>
<AdvancedSettings name=" Blabla2"/>
</advancedSettings>
</test>
</btm>

Thhis is what I got which is wrong. I want the text file elements as attributes not elements`

You can compose XML dynamically on the fly via LINQ to XML.

It is available in the .Net Framework since 2007.

c#

void Main()
{
    // static part
    XElement xelem = new XElement("BottomAssembly",
        new XElement("Tool",
        new XAttribute("toolID", "abc"),
        new XAttribute("IsMWDTool", "true"),
        new XAttribute("slaveAddress", "0"),
        new XAttribute("compressionType", "9")
        )
    );
    Console.WriteLine(xelem);

    // add XML attributes dynamically as you wish, loop through *.txt file, etc.
    xelem.Element("Tool").Add(new XAttribute("TimeIntervalMin", "206"));
    xelem.Element("Tool").Add(new XAttribute("GroupID", "18"));
    Console.WriteLine(xelem);
}

Output

<BottomAssembly>
  <Tool toolID="abc" IsMWDTool="true" slaveAddress="0" compressionType="9" />
</BottomAssembly>

<BottomAssembly>
  <Tool toolID="abc" IsMWDTool="true" slaveAddress="0" compressionType="9" TimeIntervalMin="206" GroupID="18" />
</BottomAssembly>
